Species of Epimedium extract available in China

The Epimedium species have been used extensively in Traditional Chinese Medicine for their warming or "Yang" tonic effect, which shows great therapeutic properties for the kidney, enhances the immune system, and increases sperm production, thereby acting sexual enhancement. Up to date, over 60 species of Epimedium have been reported, but only five of these are recorded in the Chinese Pharmacopeia, namely, Epimedium bravicornum Maxim., Epimedium sagittatum Maxim., Epimedium koreanum Nakai, Epimedium pubescens Maxim. and Epimedium wushanense T.S.

Constituents of Epimedium extract

There are many other ingredients in epimedium extract as well, such as flavones, Quercetin, Ikarioside A and B (wanshanense), Anhydroicaritin, Desmethylanhydroicaritin, Sagittatoside B , Diphylloside A and B, etc. Flavonoids are the main active chemical constituents of Epimedium species, the four major flavonoids contributing to their effects being epimedins A, B, and C, and icariin. These biologically active constituents are flavonol glycosides with an isoprenyl group substituted on carbon 8. However, analysis of natural health products currently available on the market containing Epimedium relys mostly on the presence of icariin. CPC established characteristic Rapid Resolution Liquid Chromatography (RRLC) profiles for complex mixtures of flavonoids from Epimedium species. The Zorbax Eclipse XDB column is able to fully separate four major flavonoids, which are epimedins A, B, and C, and icariin, for both quantitative and qualitative analysis in less than 3 minutes.

How does epimedium extract work?

Research has shown that Epimedium extract can inhibit an enzyme called acetylcholinesterase (AChE). AChE rapidly stops neurotransmission at cholinergic synapses like those found in the brain and at neuromuscular junctions, which are needed for speedy responses in the neuromuscular system. By inhibiting AChE, Horny Goat Weed supports higher levels of the key cholinergic neurotransmitters associated with sexual arousal.
